APT Groups1
<b>Description of MISP:</b> This threat actor targets South Korean think tanks, industry, nuclear power operators, and the Ministry of Unification for espionage purposes.<br><br><b>Description of Mitre:</b> Kimsuky is a North Korean-based threat group that has been active since at least September 2013. The group focuses on targeting Korean think tank as well as DPRK/nuclear-related targets. The group was attributed as the actor behind the Korea Hydro & Nuclear Power Co. compromise.[1][2]<br><br><b>Description of Etda:</b> (Kaspersky) For several months, we have been monitoring an ongoing cyber-espionage campaign against South Korean think-tanks. There are multiple reasons why this campaign is extraordinary in its execution and logistics. It all started one day when we encountered a somewhat unsophisticated spy program that communicated with its “master” via a public e-mail server. This approach is rather inherent to many amateur virus-writers and these malware attacks are mostly ignored.<br><br>
